Abstract (en)
[origin: WO2010097440A1] The device according to the invention includes a pair of counter-rotating propellers suitable for being modified by an actuator (31) located in a central recess of the shafts. The system for transporting energy to the actuator (31) includes a conduit (34) entering a static casing (5) in the proximity of a planetary gear train (17), as well as control ducts (38) leading to the actuator (31) and passing through the planet carrier (14) of a planetary gear train (17). The junction is provided by a dynamic seal with a manifold. Said path avoids the high-temperature turbine.
